Electro18 posted a tutorial on how to make a portable digital optical tachometer using an Arduino Uno, an instructable here: A tachometer is a device used to measure the RPM or Revolutions Per Minute of any rotating body. Tachometers can be contact based or non-contact ones. The non-contact or contact-less optical tachometers usually use laser or Infrared […]

blueShift – An OpenXC LED tachometer
In this video Pete Mills demonstrates his blueShift project, an OpenXC LED tachometer he is working on: An Arduino, some addressable LED’s, a bluetooth module, code and a 3D printer come together to make blueShift – An OpenXC LED Tachometer. blueShift is so named for the Bluetooth protocol used for data communication, and the use of […]
Home-brew milling machine tacho
Wardy writes: Why buy a tacho when you can build one? I thought it would be a cool project and there happens to be a convenient spot on top of the machine for a tacho to live. I fired up my pen and paper and wrote some code to do the requisite calculations. Then threw […]
Arduino IR tachometer
Chris from Pyroelectro has posted this tutorial detailing the use of an IR transmitter and receiver break-beam pair to measure the speed of a fan. The IR components are used in conjunction with the Arduino UNO which processes the break-beam interruption counting with the result displayed on a 16×2 LCD display. You can get the […]
